Endoscopic sphincterotomy in acute biliary pancreatitis: A question of anesthesiological risk

Two consecutive surveys of acute pancreatitis in Italy, based on more than 1000 patients with acute pancreatitis, reported that the etiology of the disease indicates biliary origin in about 60% of the cases. The United Kingdom guidelines report that severe gallstone pancreatitis in the presence of increasingly deranged liver function tests and signs of cholangitis (fever, rigors, and positive blood cultures) requires an immediate and therapeutic endoscopic retrograde cholangiopancreatography (ERCP). These guidelines also recommend that patients with gallstone pancreatitis should undergo prompt cholecystectomy, possibly during the same hospitalization. However, a certain percentage of patients are unfit for cholecystectomy because advanced age and presence of comorbidity. We evaluated the early and long-term results of endoscopic intervention in relation to the anesthesiological risk for 87 patients with acute biliary pancreatitis. All patients underwent ERCP and were evaluated according to the American Society of Anesthesiology (ASA) criteria immediately before the operative procedure. The severity of acute pancreatitis was positively related to the anesthesiological grade. There was no significant relationship between the frequency of biliopancreatic complications during the follow-up and the ASA grade. The frequency of cholecystectomy was inversely related to the ASA grade and multivariate analysis showed that the ASA grade and age were significantly related to survival. Finally, endoscopic treatment also appeared to be safe and effective in patients at high anesthesiological risk with acute pancreatitis. These results further support the hypothesis that endoscopic sphincterotomy might be considered a definitive treatment for patients with acute biliary pancreatitis and an elevated ASA grade.     

Imaging tests for accurate diagnosis of acute biliary pancreatitis

Gallstones represent the most frequent aetiology of acute pancreatitis in many statistics all over the world, estimated between 40%-60%. Accurate diagnosis of acute biliary pancreatitis(ABP) is of outmost importance because clearance of lithiasis [gallbladder and common bile duct(CBD)] rules out recurrences. Confirmation of biliary lithiasis is done by imaging. The sensitivity of the ultrasonography(US) in the detection of gallstones is over 95% in uncomplicated cases, but in ABP, sensitivity for gallstone detection is lower, being less than 80% due to the ileus and bowel distension. Sensitivity of transabdominal ultrasonography(TUS) for choledocolithiasis varies between 50%-80%, but the specificity is high, reaching 95%. Diameter of the bile duct may be orientative for diagnosis. Endoscopic ultrasonography(EUS) seems to be a more effectivetool to diagnose ABP rather than endoscopic retrograde cholangiopancreatography(ERCP),which should be performed only for therapeutic purposes.As the sensitivity and specificity of computerized tomography are lower as compared to state-of-the-art magnetic resonance cholangiopancreatography(MRCP)or EUS,especially for small stones and small diameter of CBD,the later techniques are nowadays preferred for the evaluation of ABP patients.ERCP has the highest accuracy for the diagnosis of choledocholithiasis and is used as a reference standard in many studies,especially after sphincterotomy and balloon extraction of CBD stones.Laparoscopic ultrasonography is a useful tool for the intraoperative diagnosis of choledocholithiasis.Routine exploration of the CBD in cases of patients scheduled for cholecystectomy after an attack of ABP was not proven useful.A significant rate of the so-called idiopathic pancreatitis is actually caused by microlithiasis and/or biliary sludge.In conclusion,the general algorithm for CBD stone detection starts with anamnesis,serum biochemistry and then TUS,followed by EUS or MRCP.In the end,bile duct microscopic analysis may be performed by bile harvested during ERCP in case of recurrent attacks of ABP and these should be followed by laparoscopic cholecystectomy.     

ERCP in acute pancreatitis

BACKGROUND: The role of endoscopic retrograde cholangiopancreatography (ERCP) in the management of acute pancreatitis has evolved over years since its introduction in 1968. Its importance in diagnosing the etiology of pancreatitis has steadily declined with the advent of less invasive diagnostic tools. The therapeutic implications of ERCP in acute pancreatitis are many fold and are directed towards management of known etiological factors or its related complications. This article highlights the current status of ERCP in acute pancreatitis. DATA SOURCES: An English literature search using PubMed database was conducted on ERCP in acute pancreatitis, the etiologies and complications of pancreatitis amenable to endotherapy and other related subjects, which were reviewed. RESULTS: ERCP serves as a primary therapeutic modality for management of biliary pancreatitis in specific situations, pancreatitis due to microlithiasis, specific types of sphincter of Oddi dysfunction, pancreas divisum, ascariasis and malignancy. In recurrent acute pancreatitis and smoldering pancreatitis it has a definite therapeutic utility. Complications of acute pancreatitis including pancreatic-duct disruptions or leaks, benign pancreatic-fluid collections and pancreatic necrosis can be beneficially dealt with. Intraductal ultrasound and pancreatoscopy during ERCP are useful in detecting pancreatic malignancy. CONCLUSIONS: The role of ERCP in acute pancreatitis is predominantly therapeutic and occasionally diagnostic. Its role in the management continues to evolve and advanced invasive procedures should be undertaken only in centers dedicated to pancreatic care.

Role of endoscopic ultrasound during hospitalization for acute pancreatitis

Endoscopic ultrasound(EUS)is often used to detect the cause of acute pancreatitis(AP)after the acute attack has subsided.The limited data on its role during hospitalization for AP are reviewed here.The ability of EUS to visualize the pancreas and bile duct,the sonographic appearance of the pancreas,correlation of such appearance to clinical outcomes and the impact on AP management are analyzed from studies.The most important indication for EUS appears to be for detection of suspected common bile duct and/or gall bladder stones and microlithiasis.Such an approach might avoid diagnostic endoscopic retrograde cholangio-pancreatography with its known complications.The use of EUS during hospitalization for AP still appears to be infrequent but may become more frequent in future.

Strategy to differentiate autoimmune pancreatitis from pancreas cancer

Autoimmune pancreatitis (AIP) is a newly described entity of pancreatitis in which the pathogenesis appears to involve autoimmune mechanisms. Based on histological and immunohistochemical examinations of various organs of AIP patients, AIP appears to be a pancreatic lesion reflecting a systemic "IgG4-related sclerosing disease". Clinically, AIP patients and patients with pancreatic cancer share many features, such as preponderance of elderly males, frequent initial symptom of painless jaundice, development of new-onset diabetes mellitus, and elevated levels of serum tumor markers. It is of uppermost importance not to misdiagnose AIP as pancreatic cancer. Since there is currently no diagnostic serological marker for AIP, and approach to the pancreas for histological examination is generally difficult, AIP is diagnosed using a combination of clinical, serological, morphological, and histopathological features. Findings suggesting AIP rather than pancreatic cancer include: fluctuating obstructive jaundice; elevated serum IgG4 levels; diffuse enlargement of the pancreas; delayed enhancement of the enlarged pancreas and presence of a capsule-like rim on dynamic computed tomography; low apparent diffusion coefficient values on diffusion-weighted magnetic resonance image; irregular narrowing of the main pancreatic duct on endoscopic retrograde cholangiopancreatography; less upstream dilatation of the main pancreatic duct on magnetic resonance cholangiopancreatography, presence of other organ involvement such as bilateral salivary gland swelling, retroperitoneal fibrosis and hilar or intrahepatic sclerosing cholangitis; negative work-up for malignancy including endoscopic ultrasound-guided fine needle aspiration; and steroid responsiveness. Since AIP responds dramatically to steroid therapy, accurate diagnosis of AIP can avoid unnecessary laparotomy or pancreatic resection.

磁共振胰胆管成像和直接胰胆管造影对胆胰疾病诊断价值自身对比的前瞻性研究

目的 比较直接胰胆管造影（ERCP和PTC）和磁共振胰胆管成像（MRCP）对胆胰疾病的诊断价值。方法 临床怀疑胆胰系疾病63例。每例先行MRCP,在此后24h内行ERCP。影像科和内镜医师分别报告自己所见结果,待研究结束后,以ERCP或PTC为参照标准统一对比分析。结果 63例行ERCP中,成功率为88.9%（56/63例）,7例ERCP失败者改行PTC检查成功;所有MRCP均获成功,成功率为100.0%;MRCP的灵敏度为98.2%、特异度83.3%、误诊率为16.7%、漏诊率为1.8%。MRCP和ERCP（或PTC）总符合率85.7%,其中在胆系结石及胆管肿瘤分别为100.0%和92.9%,乳头病病变为70.6%（12/17例）,在慢性胰腺炎和肝吸虫的诊断符合率分别为3/3和66.7%。63例ERCP者,术后并发胰腺炎5例、肾周脓肿1例（为B-Ⅱ术后）,并发症发生率为9.5%（6/63例）;而MRCP无并发症发生。结论 对胆管内疾病,MRCP可达到ERCP的单纯诊断水平,而对乳头部病变（尤其是小病变）和肝吸虫,MRCP却无法与ERCP相比拟。对不能耐受ERCP及禁忌症者,MRCP是较好的选择。MRCP的最大不便在于不能同时进行治疗。     

Relapses of biliary acute pancreatitis in patients with previous attack of biliary pancreatitis and gallbladder in situ

AIM: To evaluate relapse of acute pancreatitis in patients with biliary pancreatitis in whom coexisting diseases or patient refusal have excluded cholecystectomy. PATIENTS AND METHODS: Forty-seven patients presenting a first episode of biliary acute pancreatitis underwent urgent endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic sphincterotomy (ES). RESULTS: ERCP with ES was successful in all but one patient (97.8%) who was then cholecystectomised. Complications related to the endoscopic procedure were reported in five patients (10.6%). During the follow-up period (median time 12 months; range 1-84 months), 10 patients (21%) suffered from biliary complications. Three patients (6.4%), all with lithiasis of the gallbladder, had relapses of acute pancreatitis, two of them within 2 months of the previous episode, and one about a year later after ingestion of a rich meal and alcoholic beverages. The first two were cholecystectomised. Two patients died during the follow-up period from unrelated diseases. CONCLUSIONS: In subjects who are at high risk for anaesthesia, endoscopic procedures may be utilised.     

Factors and outcomes associated with pancreatic duct disruption in patients with acute necrotizing pancreatitis

Background and aimsAcute necrotizing pancreatitis (ANP) can affect main pancreatic duct (MPD) as well as parenchyma. However, the incidence and outcomes of MPD disruption has not been well studied in the setting of ANP.MethodsThis retrospective study investigated 84 of 465 patients with ANP who underwent magnetic resonance cholangiopancreatography and/or endoscopic retrograde cholangiopancreatography. The MPD disruption group was subclassified into complete and partial disruption.ResultsMPD disruption was documented in 38% (32/84) of the ANP patients. Extensive necrosis, enlarging/refractory pancreatic fluid collections (PFCs), persistence of amylase-rich output from percutaneous drainage, and amylase-rich ascites/pleural effusion were more frequently associated with MPD disruption. Hospital stay was prolonged (mean 55 vs. 29 days) and recurrence of PFCs (41% vs. 14%) was more frequent in the MPD disruption group, although mortality did not differ between ANP patients with and without MPD disruption. Subgroup analysis between complete disruption (n = 14) and partial disruption (n = 18) revealed a more frequent association of extensive necrosis and full-thickness glandular necrosis with complete disruption. The success rate of endoscopic transpapillary pancreatic stenting across the stricture site was lower in complete disruption (20% vs. 92%). Patients with complete MPD disruption also showed a high rate of PFC recurrence (71% vs. 17%) and required surgery more often (43% vs. 6%).ConclusionsMPD disruption is not uncommon in patients with ANP with clinical suspicion on ductal disruption. Associated MPD disruption may influence morbidity, but not mortality of patients with ANP. Complete MPD disruption is often treated by surgery, whereas partial MPD disruption can be managed successfully with endoscopic transpapillary stenting and/or transmural drainage. Further prospective studies are needed to study these items.     

Utility of pancreatography for diagnosing autoimmune pancreatitis

RESULTS: The following ERCP findings suggested a diagnosis of AIP rather than PC. Obstruction of the main panc...     

应用EST技术治疗急性胆源性胰腺炎的临床体会

目的 探讨内镜下乳头Oddi括约肌切开术(endoscopic sphincterotomy,EST)在急性肌源性胰腺炎(acute gallstone pancreatitis,AGP)诊治中的应用价值。方法 将入选的189例AGP患者随机分为EST治疗组(n=79)和对照组(n=110),并根据APACHE Ⅱ评分,将每组再进一步分为重症组和轻症组,两组患者均给予中西医结合治疗。EST治疗组在入院后24h内行内镜逆行胰胆管造影(endoscopic retrograde cholangiopancreatography,ERCP)+EST,如发现胆总管或胆胰共同通道有结石,则行网篮、气囊取石或碎石器碎石后取石,如结石多、结石直径大或取石未净,则EST术后再行鼻胆管引流术(endoscopic nasobilliary drainage,ENBD)。结果 对重症AGP,EST治疗组的并发症发生率转开腹手术率、住院天数及住院费用均明显低于对照组(P<0.05);而轻症AGP,两组之间无显著差异结论 早期应用EST技术治疗重症AGP是有效的和安全的。     

磁共振胰胆管造影、超声内镜与逆行胰胆管造影诊断阻塞性黄疸的价值

目的：比较磁共振胰胆管造影（MRCP）、超声内镜（EUS）与内镜逆行胰胆管造影（ERCP）诊断阻塞性黄疸的价值。方法：39例阻塞性黄疸患者分别行MRCP、EUS和ERCP。MRCP采用重T2加权及超快速自旋回波水成像技术进行,EUS和ERCP按常规进行。结果：MRCP、EUS与ERCP诊断准确率分别为87．2％（34／39例）、94．9％（37／39例）和97．4％（38／39例）;对恶性狭窄的诊断准确率分别为61．5％（8／13例）、84．6％（11／13例）和92．3％（12／13例）;对胆总管结石的诊断准确率均为100．0％（21／21例）。结论：MRCP为无创性检查,在明确阻塞性黄疸病因时可作为首选方法,目前尚不能取代ERCP。EUS作为诊断胆、胰系统疾病的重要方法,与MRCP和ERCP结合,能提高阻塞性黄疸诊断 的准确率。     

Management of patients after recovering from acute severe biliary pancreatitis

Cholelithiasis is the most common cause of acute pancreatitis,accounting 35%-60% of cases. Around 15%-20% of patients suffer a severe attack with high morbidity and mortality rates. As far as treatment is concerned,the optimum method of late management of patients with severe acute biliary pancreatitis is still contentious and the main question is over the correct timing of every intervention. Patients after recovering from an acute episode of severe biliary pancreatitis can be offered alternative options in their management,including cholecystectomy,endoscopic retrograde cholangiopancreatography(ERCP) and sphincterotomy,or no definitive treatment. Delaying cholecystectomy until after resolution of the inflammatory process,usually not earlier than 6 wk after onset of acute pancreatitis,seems to be a safe policy. ERCP and sphincterotomy on index admission prevent recurrent episodes of pancreatitis until cholecystectomy is performed,but if used for definitive treatment,they can be a valuable tool for patients unfit for surgery. Some patients who survive severe biliary pancreatitis may develop pseudocysts or walled-off necrosis. Management of pseudocysts with minimally invasive techniques,if not therapeutic,can be used as a bridge to definitive operative treatment,which includes delayed cholecystectomy and concurrent pseudocyst drainage in some patients. A management algorithm has been developed for patients surviving severe biliary pancreatitis according to the currently published data in the literature.

Role and timing of endoscopy in acute biliary pancreatitis

The role and timing of endoscopy in the setting of acute biliary pancreatitis (ABP) is still being debated. Despite numerous randomized trials have been published, there is an obvious lack of consensus on the indications and timing of endoscopic retrograde cholangiopancreatography (ERCP) in ABP in meta-analyses and nationwide guidelines. The present editorial has been written to clarify the role of endoscopy in ABP. In clinical practice the decision to perform an ERCP is often based on biochemical and radiological criteria despite they already have been shown to be unreliable predictors of common bile duct stone presence. Endoscopic ultrasonography (EUS) is not currently a worldwide standard diagnostic procedure early in the course of acute biliary pancreatitis, but it has been shown to be accurate, safe and cost effective in diagnosing biliary obstructions compared with magnetic resonance cholangiopancreatography and ERCP and therefore in preventing unnecessary ERCP and its related complications. Early EUS in ABP allows, if appropriate, immediate endoscopic treatment and significant spare of unnecessary operative procedures thus reducing possible related complications.
